Thread: pgsql: Move BitmapTableScan per-scan setup into a helper

Move BitmapTableScan per-scan setup into a helper

Add BitmapTableScanSetup(), a helper which contains all of the code that
must be done on every scan of the table in a bitmap table scan. This
includes scanning the index, building the bitmap, and setting up the
scan descriptors.

Pushing this setup into a helper function makes BitmapHeapNext() more
readable.
